Serious question!
Do flats have to be taken at same FL and f ratio as imaging run? I'm thinking about lens imaging here. |
In answer to your question you may refer to Jim Solomon's Astrophotography Cookbook
Flat Darks- exactly same value ISO and Tv settings when collecting flat lights but with eyepiece cover and lens cap in place
I noticed that you are using a Pentax stD I have recently purchase the K100d super. What program do you use to stack photo's. Also is it a good idea to set ISO to 800 etc and do muliptle short shots
